chine is provided. in the ordinary way with a series of keys, the bars of which have pro jections, which on the depression of the keys encounter yokes and thereby rock these latter. These yokes have joints and con"- plings and are connected with the coin ejec-. tors, so that on turning the handle the adjusted coins can be ejected. New in accordance with this invention the ejectors 1 are loosely mounted on bushings 2 of the operating shaft iend divided into a number of groups, preferably four groups, one for each of the gold coins, the dollars, the fifty cents and the ten and five cent pieces and copper money. For each of these groups on the operating shaft a coupling l, 5, 6 and 7 isprovided which is thrown into action onthe corresponding keys being operated..- A coupling 8 is also provided for each ejector 1, which ejectors are all in the coupling position when the machine is not operated. Each ejector 1, as shown in Fig. 1, is further connected with a double-armed lever 9 which 15 loosely mounted on the bushing 51,

one part of the le er being pivotally connected with the ejector 1, While theotl er end is formed as a slotted'guide 10. In this slot 10 a roller which serves as coupling,

. mounted on the bushing 2.

The handle 17 for operating the operating shaft 3 has a safety mechanism, in order that the crank 17 cannot be rotated at will. This safety device substantially consists of a cam 18 which lies within reach of a stud 19 on the crank 17, so that this cannot be ro-,

tated. Now in order to release the stop 19, the cam 18 is provided with yokes 20 and 21, on which all the sale keys 24 and 26 press and thereby rock the cam 18 in such a way that it releases the stop 19 and the handle may be operated. If, for instance, by means of the handle 17 the operating shaft 3 be given an oscillation, only the lever 13 with itsslotted guides 14 is lifted and as no keys are depressed, that is to say none of the group couplings l7 are coupled, this lifting of the lever has no further influence on the ejector. If on the other hand one of the couplings 4-7 be thrown into action, their coupling roller travels forward -in the slotted guide of the lever 16 and thus reaches the slot 14 of the lever 13, so that when the machine is again operated by means of the handle 17, the lever 13 takes the coupling roller 4 or 5, 6 or 7 respectively with it and thus carries with it also all the levers 22 which are firmly mounted on the bushing 2 in question.

As already mentioned all the couplings 8 I are coupled for the ejectors 1, so that all the levers 22 lift all the respective rollers 8 and operate the double levers 9 and thereby theejcctors 1, but of course only those ejectors which belong to the coupled group. Now one, several of or all the groups of couplings 4, 5, 6 or 7 may be simultaneously coupled.

and by depressing a number of keys the ejector couplings 8 uncoupled, so that when the handle is operated only those ejectors 1 operate, the groups of couplings belonging to which firstly and then. the e ector coupling 8 secondly, are coupled.

The series of keys consist of the separate sets of keys for the dollar receipts 23, dollar sales 22L, cent receipts 25 andcent sales 26, the borrowing of an already adjusted amount taking place automatically in the then succeeding transfer to a subordinate kind of money such as from dollars to cents or tens to units. No separate keys are thus necessary, such as had hitherto to be operated. For this object the yokes which act in conjunction with the keys 23, 24, 25 and 26 are differently shaped and provided with suitable devices. Thus, for instance all. the yokes'27 which operate the ten cent ejectors are provided with spring forks 28 which have links 29 and 30 on both sides, the links 29 being releasably connected with the ejeetors 1 while the links 30 may be brought into connection with grippers 31 which, if necessary, push the links 29 and 30 and the latter are for this object provided with pins 32. The fork 28 turns on a pivot 7 8'which is mounted in. the tllblll: yol 27 and the fork 28, after it has been depressed by a key, is in spite of that again returned to the initial position by a spring 7 9.

The before men'tioned grippers 31 only come into operation when the fifty cents sale key is depressed, which operates a yoke which rocks on a shaft 34 and thus operates a frame 35 which lifts the joint 30 for the four tens ejector-s 1 and brings them within reach of the gripper 31, as the four tens cou plings 8 are released, while the yokes 27 draw back the links 29 and 30 and rollers 8 and simultaneously displace the links in such a way that their pins 32 come to lie in the grippers 31. As of course the fifty cents sale key also encounters the yoke 20 and'this releases the crank 17 after the crank 17 has been turned only the ejector of the fifty cents piece is operated, as only one .coin group of fifty cents and fourtens are coupled, the four tens are, however, as previously described uncoupled. If, however, in addition to the fifty cents sale key, for instance, the five cents key be depressed, the

following action takes place: All the units sale keys press on the yokes 36 and 37 the yoke 36 again coupling the 4 tens by means of the gripper 31, while the yoke 37 throws out of action the link'iO of the 50 cents coupling by means of a gripper 38 and a pin 39, so that now 4 tens stand ready for ejecting. A yoke 41 is, however, operated when the five cents sale key is depressed, on which yoke all the cents sale keys press, the yoke 41 throwing into action the coupling 6. The five cents sale key also presses in known manner on the yokes-11 in such a way that iis five cents piece are ejected, that is to say forty-five cents which is correct.

' A yoke 42 is also provided, which is firmly mounted on a shaft 43 of a yoke 44, see Fig. 2, and serves foruncoupling a one dollar ejector 1 when a key of the cents sale is depressed. On the same shaft 43 a yoke 45 is lobsely mounted, which serves for coupling the coin group with the four'tens and the one fifty cents piece.

As already mentioned two of coins are provided, namely one for go (1 and for dollars. Inorder to cause these to operate in the correct way, separate and similar devices and yokes are provided equally further grou s as in the'two other 'yoke 47 is provide for instance, loosely cups of coins. Thus a mounted'on the shaft 46, which yoke is coupled by means of'a link 48 with the coupling 4&0: the. gold. coin group.

Threeyokes 50, 51 and 52-which. form to a pertain extent a shaftin three parts and serve tor-the following. objects, are mounted, one firmly and the others loosely, on a shaft 49. The yoke 50 is loosely mounted on the shaft 49-and this is provided. with a link or joint 53 which couples the dollars coin group.- For this. object a cam 54 is firmly arranged on the shaft 49, which cam is under the action of a spring 55 and rests on the yoke 50. The link 53 is also connected by a fork 56 with the shaft 49, so that on the operation of the yoke 50 the ring. 55 presses down the cam 54, whereby t e shaft 49 turns and thus displaces the link 53, that is. to say I the coupling 5 for the dollars coin group is coupled. The'yoke 51 is also loosely mounted onthe shaft 49, on which yoke a cam 57 alsorests, the spring 58 of which is however, so strong that it overcomes the spring I515 13- e cam 57 is lowered and then the shaft 49 rocks, that is to say the previously coupled dollar coin group is again uncoupled. The third yoke 52 which is firmly mounted onthe shaft 49 has for its object, on the operation of the yoke 52, to again rock the shaft 49, whereby the dollar coin glwonp is again coupled. .The following examples will serve for the better comprehension of this First ewample-twenty dollars received, ten dollars saZe.-As soon as the $20 re ceived key is depressed the couplingof the old coin group is coupled by the yoke47. imgiltaneously, however, by the same key the yoke is operated, which throws into action the dollar coin group. Now ifthe $10 sales key be depressed, it operates the yoke 51, which then, as already described,

uncouples the coupling 5 and the dollars coin group, so that on operating the handle $10 in gold is ejected. A similar device as with the four tens is also provided with This device consists of a yoke 59 which is firmly mounted on a shaft 60 and when operated lifts a frame 61. This frame 61 lifts a link 62 which is connected with the link 63, and as the link 62 has a 64, the latter comes within reach-of a gripper 65 which is mounted on a yoke 66, Now if the yoke 66 loosely mounted on the shaft 60 be depressed, it draws back by means of its gripper 65 the links 62 and 63, that is to say the $10 ejector" is uncoupled.

Second .ezmmpletwenty dollars receioed, 15 dollars saZe.-The $20 received key is depressed and it operates the two yokes 47 and 50, so that the coin group couplings '4 and 5 for gold and dollars are ready to be ejected. The-$10 sales key, however, also depresses the yoke 59 and this latter by means of its frame 61 lifts thelink 62. All the one dollar sales keys press on the yokes 52 and 66. Now as soon as the five dollars sales key is depressed, the yoke 52 again throws into action the dollar coin group and the yoke 66 draws back the coupling 4 for the old coin group. The five dollars sales ey also presses in known manner with its projections on the yoke, 11 and draws five dollars fromthe coupled dollar coin (group, so that when the handle is turne $5 are ejected. If, for instance, 65 cents is the amount of the sale, the 60 cents sales key, like all the tens sales keys presses on a yoke 80 which operates a shaft 81, this latter lifting a frame 82, so that the link is also lifted, by a gripper 84 engaging behind its pin 83. Now when the five cents sales key is depressed it operates the yoke 37, so that only one ton is uncoupled by the gripper 84, and only three tens stand ready or ejection. The five sales key of the respective coin group has also, however, uncoupled four one cents, so that when a dol- 1211' is received and the sale is sixty-five cents, thirty-five cents are ejected. As soon as the dollar amount received is equal to the amount of dollar sale, for the correct operation of the machine, the always adjusted one dollar ejector must be uncoupled. For this object an equivalent dollar received key 23 and dollar sales key 24 are releasably connected with one another by bars 67 and 68, of which the bar 67 turns in a bearing 69 on a pivot 70 and carries a pressure roller 71, while the one bar 68 has a slot 72 into' which a pin 73 of the bearing 69 extends and serves as a guide. Now the key bars 23 and 24 are provided with slots, 74, one bar 67 always resting in the slot 74,

while the bar 68 is only inserted. in the slot 74 of the sales key 24 by means of the pressure roller 71 and the beveling 75 of the rod 68 when the receipts key 23 is depressed. On the. sales key 24 being depressed, the rod 68 is carried with it and this presses on a bar 76 standing under the action of a spring, which bar then operates and uncouples the yoke 44 of the one dollar ejector. The bars 67 and 68 are also under the action of a spring 77.
